Open-Access Experimental Data Collection of Fixed OWC and Wells Turbine Performance
Description
The experimental data generated during this study are compiled into a comprehensive dataset collection aimed at providing full transparency and supporting future benchmarks in the field of Wave Energy Converters, specifically for Oscillating Water Column type. The dataset comprises the time-series obtained from the scaled 1:13 Mutriku Wave Power Plant (MWPP) model, equipped with a Wells turbine tested in a real time hardware-in-the-loop (HIL). The testing campaign evaluated the system across a broad spectrum of operating conditions to characterise its hydrodynamic and thermodynamic performance. By dynamically adjusting the physical orifice size in real time to emulate the linear damping charactertistic of the Wells turbine, the HIL framework enabled the testing of various valve configurations and control strategies. These tests aimed to evaluate overall system performance under realistic operational conditions by effectively capturing the coupled dynamics between the physical system and the power take-off (PTO) unit. The dataset collection is categorised into three distinct control and pneumatic configurations developed into HIL framework: 1. Baseline Control (ctrl_base.mat): This configuration serves as the standard operational reference case, implementing a conventional control strategy tailored for nominal Wells turbine operation. 2. Wave-to-Wire Control (ctrl_w2w.mat): This case apply a control strategy designed to optimise the complete energy conversion chain from wave resource to electrical output. 3. Baseline Control with Damping Valve (ctrl_base_damp.mat): This configuration pairs the standard baseline control with a damping valve acting in series to limit peak pressure. Additionally, to provide a benchmark independent of the active HIL loop (and to evaluate the hydrodynamic chamber response under quadratic damping typical of impulse turbines), a static physical testing case is included: 4. Fixed Orifice (fixed_orifice.mat): Tests conducted across four discrete orifice diameters to isolate and evaluate the chamber hydrodynamic response under fixed pneumatic damping conditions.
